Spam is the biggest threat to organic search engines, whose goal is to provide quality search results for keywords or phrases entered by their users. Google's PageRank algorithm update ("BigDaddy") in February 2006—the final stage of Google's major update ("Jagger") that began in mid-summer 2005—specifically targeted spamdexing with great success. This update thus enabled Google to remove a large amount of mostly computer-generated duplicate content from its index.[29]

As an affiliate marketer, there are many dos and don’ts when it comes to marketing products. The Affiliate Marketing Diploma Course guides you through appropriate marketing of products, how to track the performance of your affiliate scheme, and why content should come first. You’ll discover ways to drive traffic to your site and improve your affiliate marketing performance, with special attention paid to conversion rates.
One of the most sought after and highly recommended course is this one on Guide to Effective Affiliate Marketing Strategies by Kudus Adu. Not only does he focus on create an affiliate marketing strategy, he focuses on best practices to create money pages, tells you how to build your email marketing list and how to profit from it. He clearly asks people looking for ‘get rich quick strategies’ to stay away from the course. More details here.
Next, I’m going to walk you through the information that’s in this box, because this is a lot of information in this little box and it can get overwhelming if you don’t know what all these terms mean. The first thing you want to pay attention to is the average amount of money per sale. This is not how much the product costs; this is how much an affiliate makes on average for one sale of that product. When you look at the stats line, this basically drills that down into a little bit more detail. The initial sale is $20.65. Why does this go all the way up to $26.80? That’s because there’s a re-bill feature. What that is, is basically they buy the product, and then there’s an add-on or another option for that person to sign up to some membership site, and that’s how much they make on average from the re-bill. If you average everything together, this is how much the affiliate makes with everything considered.
Websites consisting mostly of affiliate links have previously held a negative reputation for underdelivering quality content. In 2005 there were active changes made by Google, where certain websites were labeled as "thin affiliates".[30] Such websites were either removed from Google's index or were relocated within the results page (i.e., moved from the top-most results to a lower position). To avoid this categorization, affiliate marketer webmasters must create quality content on their websites that distinguishes their work from the work of spammers or banner farms, which only contain links leading to merchant sites.
